How do i use this?

This is set by the os and colorsync.

The 'Displays' preferences allow you to set a calibration for each screen.
this is what the calibration effects.

There is a rather good piece of software called 'Profile Maker Editor' from GregTabMacbeth that allows you to make a curve in any shape you want.

You cold use this to create a screen profile that was optimal for a DL1 in certain conditions.
